DEVICE FOR CASTING HOOKS.

SPECIFICATION forming part of Letters Patent No. 450,757, dated April21, 1891.

Application filed January 17, 1891- .Serial No. 878,143. (No model.)

To aZZ whom it may concern.-

Be it known that I, EDMUND KUHN, a citizen of the United States,residing at New Albany, in the county of Floyd, State of Indiana, haveinvented certain new and useful Improvements in Devices for CastingHooks, of which the following is a specification, reference being hadtherein to the accompanying drawings. a

This invention relates to certain new and useful improvements in devicesfor casting hooks or catches upon articles, such as fender-rails,foot-rails for stoves, and other devices, which require a catch to holdthem in place.

The objects and advantages of the inven tion will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which Figure 1 is a side elevation showing thepattern in the sand. Fig. 2 is a central section through the tool whichforms the catch in the mold. Fig. 3 is a perspective of the said toolremoved. Fig. 4 shows a portion of the casting.

Like letters of reference indicatelike parts in the different views inwhich they are shown.

In the said drawings, A designates the pattern, which is provided with ashoulder a, beyond which is a lug h, as seen clearly in Fig. 1. Inpractice this pattern is placed in the sand B, as indicated in Fig. 1.\Vhen the impression has been made, the pattern is removed and the tool0 is placed in the depression formed by the said pattern, as seen inFig. 2. This tool consists of a tapered tubular or cylindrical metalportion, the metal of which at one side is extended to form a handle 0,by which the tool may be manipulated. The smaller end is provided with aslot d and the larger end with a slot c, as shown in Fig. 2. The tubularbody of the tool conforms in contour with the pattern, so that it willjust fill the opening made by the pattern in the sand. W'ithin the bodyof the tool are the lugs or ears f, between which is pivoted 011 thetransverse pins g, held in said ears or lugs, the lever B, one end ofwhich extends through the slot in the larger end of the body of thetool, as seen in Fig. 2, and the other end extends through the slot inthe smaller end of said body, as seen in the same figure, and is thereformed with a hook h, as seen in Figs. 2 and 3, which is designed toform the catch in the completed casting. Between the hook and the bottomor smaller end of the body of the tool the lever is formed withshoulders i, as seen best in Fig. 3, which serve as guides to insure themovement of the lever in a straight line. Arranged within the body ofthe tool is a spring D, which serves to normally'force the lower or hookend of the lever in the position in which it is shown in full lines inFig. 2. The lever is provided with a bulge or teat 7;, as seen in Fig.2, which engages the inner wall of the body of the tool and prevents thehook end of the lever being thrown back far enough to make a depressionin the sand with its rear face, which would destroy the contour of thefinished casting. The completed casting is shown in Fig. 4.

The operation will be apparent from the above description, when taken inconnection with the annexed drawings, and a detailed description thereofis not deemed necessary.

Various modifications in detail may be resorted to without departingfrom the spirit of the invention or sacrificing any of its advantages.For instance, the upper or larger end of the body of the tool may beentirely open instead of having acover provided with a slot, as abovedescribed,

\Vhat I claim as new is- 1. A tool for the purpose described, consistingof a body portion and a lever pivoted therein and projecting at itsends, being provided at one end with a shouldered hook and near theother end within the body portion with a bulge or teat, substantially asand for the purpose specified.

2. The tool described, consisting of the tapered tubular body portionhaving a handle,

the lever pivoted within the body portion and projecting therethrough ateach end, formed at one end with a hook and shoulders and near the otherend Within the body portion with a bulge 0r teat, and a spring withinthe body portion acting on the lever, substantially as shown anddescribed.

In testimony whereof I affix my signature in presence of two witnesses.

EDMUND KUHN.
